This invention comprises a sheet delivery mechanism in which two pro ducts of the same or of different lengths may be delivered simultaneously side by side; i

L5 This invention more particularly comprises a mechanism of the above character in which two separately operated flies are employed, means being provided for properly timing the movement of one of the flies to deliver ii longer or shorter products.

A practical embodiment of the invention is represented in the accompanying drawings, in which 7 Fig. 1 represents an end view of themultifly sheet delivery mechanism, the parts being broken away at one of the adjustable fly cams for a clearer understanding of its adjustment;

Fig. 2 represents a detail side View of the 29 delivery mechanism, and

Fig. 3 represents a detail section taken in the plane of the line III-III of Fig. 1,1001;- ing in the direction of the arrows.

The shaft 1 of the rotary sheet carrier which is shown herein as a flydelivery reel 2,

in the side frames 5, 6, which shaft may be driven from any suitable source of power (not shown herein) through the gear 7 located in the present instance at the end of the shaft outside the side frame 5. The usual reel ens gaging friction rolls 8 are carried by a cross shaft 9 mounted at its ends in upward extensions 10, 11 of the side frames 5, 6 respeccarrying a stud or roller 14 which is arranged in position to be engaged by the stationary cam 15 for operating the grippers to simultaneously take the leading edges of two sheets or two groups of sheets from the cylinder 16.

A stationary cam 17 is located in position to 45 engage the roller 1% to operate the grippers to release the leading edges of the sheets in time to allow the sheets to travel side by side down the front of their respective flies 18, 19. 50 The two flies 18, 19 are independently opertively. The sheet grippers 12 are carried by the cross shaft 13 which is mounted to rock in suitable bearings carried by the fly delivery reel 2. This shaft is provided with an arm 1 V c the reel shaft 1 and by providing the cam with ated and are arranged side by side in position to receive the sheets from the reel 2 and deliver them in two piles on the table 20. The

alined separately operated cross shafts 21, 22.

of these flies 18, 19 are mounted at their adjacent inner ends in an intermediate bearing 23 and at their outer ends in their respective bearings 24:, 25 in extensions 26, 27 of the side frames 5,6. The means for independently.

operating these fliesso that they may simultaneously handle products of the same length or ofdifl'erent lengths presented thereto side by side, are constructed, arranged and operated as follows:

Tworotatively adjustable cams 28, 29 are provided on the reel shaft 1 adjacent the side 31; which rocklever is connected by the rod '32 to a rock arm 33 on the fly shaft 21. The stud or roller is held against the face of its cam 28by the spring pressed rod 34.. Similarly, the i throughits Contact with the stud 'or roller '35 carriedby the rock lever 36; which rock lever is connected by the rod 37 with the rock arm 38 on thefly shaft 22. The stud or roller terminedlength. In the'present instance the cam 8 for the fly 18 is shown as having such an adjustment by. providing the gear 7 on which'the cam is mounted, with an elongated slot 40 concentric with the axis of rotationof a series of holes 41 throngh one of which and the slot 40 a. loclr bolt 42 may pass for clamping the cam in its desired rotative adjust- Inent. t

From the above descriptionit will be'seen that the leading edges of two productsof the same length or of different lengths and arranged side by side may be transferred simultaneously from thecylinder 16 to the grippers 12 on the fly deliveryreel. From thence these side by side productsmay pass to their fly19 is operated by the cam 29 is held against the face of its cam 29 by the spring'pressed'rod 39. S0

respective flies for delivery in two piles, side by side, on the delivery table 20. By adjusting a fly delivery cam its fly may be timed in its action to properly deliver its product of any predetermined length within prescribed limits irres ective of the movement of the other fly. or instance, the H which is to receive the shorter product wi 1 be actuated first so as to prevent the product from passing too far down the fly fingers where it would be in danger of getting out of register and also becoming wrinkled or torn, it being understood that it is desirable to start the delivery movement of the fly practically simultaneousl with the release of the tail end of the prori uct by its tension rollers 8.

It is evident that various changes ma be resorted to in the construction, form an arrangement of the several parts without departing from the spirit and scope of my invention, and hence I do not intend to be limited to the particular embodiment herein shown and described, but

What I claim is 1. Sheet delivery mechanism comprising two flies, means for transferring two products of the same or of different lengths side by side thereto and means for operating the flies.

2. Sheet delivery mechanism comprising two flies, means for transferring two products of the same or of dilferent len ths side by side thereto and cam controlled means for operating the flies.

3. Sheet delivery mechanism comprising two flies, means for transferring two products of the same or of different lengths side by side thereto and separate means for independently operating the flies.

4. Sheet delivery mechanism comprising two flies, means for transferring two products of the same or of different lengths side by side thereto and separate cam controlled means for independently operating the flies.

5. Sheet delivery mechanism comprising two flies, means for transferring two products of the same or of different lengths side by side thereto and separate means for independently operating the flies, one of said means being adjustable for properly timing the movement of its fly for productsof a pre determined length.

6. Sheet delivery mechanism comprising two flies, means for transferring two prod nets of the same or of different lengths side by side thereto and separate cam controlled means for independently operating the flies, oneof said cam controlled means being adjustable for properly timing the movement of its fly for products of a predetermined length.

7. Sheet delivery mechanism comprising two flies, a rotary carrier for transferring two products of the same or of diflerent lengths side by side thereto and means for operating the flies.

8. Sheet delivery mechanism comprising two flies, a rotary carrier for transferring two products of the same or of different lengths side by side thereto and cam controlled means for operating the flies.

9. Sheet delivery mechanism comprising two flies, a rotary carrier for transferring two products of the same or of different lengths side by side thereto and separate means for independently operating the flies.

10. Sheet delivery mechanism comprising two flies, a rotary carrier for transferring two products of the same or of different lengths side by side thereto and separate cam controlled means for independently operatin the flies.

l1. heet delivery mechanism com rising two flies, a rotary carrier for trans erring two products of the same or of different lengths side by side thereto and se )arate means for operating the flies, one 0' said means being adjustable for properly timing the movement of its fly for products of a predetermined length.

12. Sheet delivery mechanism com rising two flies, a rotary carrier for trans erring two products of the same or of different lengths side by side thereto and se arate means for operating the flies, one 0 said cam controlled means being adjustable for properly timing the movement of its fly for products of a predetermined length.

In testimony, that I claim the foregoing as my invention, I have signed my name this 16th day of May, 1930.
